Specification of Letters Patent.

Application led May 14,

To all whom it mcy concern:

Be it known that I, Gutmann C. BOHN, a citizen of thel United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful improvements in Refrigerator- Cars, of which the following' is a speciica- My invention relates to improvements in refrigerator cars of the type in which the ice containers are in the vends of the cars, its object being to provide improved construction of removable ice chamber walls which can be displaced to make, the entire length of the car available for carrying freight.

In the accompanying drawings forming part of this application, Figure l is a vertical longitudinal Section of the 'end of a car embodying my invention taken on line g/-y of Fig. 9; Figs. 2, 3 and Il are detail views of a device for supporting the movable ice chamber wall in raised position; Fig. 5 is a horizontal section on line e-z of Fig. l; Fig. 6 is a det-ail of a .hook for holding the upper end of the movable ice chamber wall in normal position; Fig. 7 is a portion of the bottom grating of the ice chamber; F ig. S is a detail view of the bottom grating of the ice` chamber illust-ratingthe means for supporting the same in raised position; Fig. 9 is a-vertical section on line -m of Fig. 5; Figs. lO, ll, and l2 are detail views illustrating the mechanism allowing the movable refrigerator wall to be raised. to a 'posit-ion underneath the roof of the car. l

In the drawings 2 represents the floor, 3 the ond wall, at the side Walls, and 5 the roof of an ordinary refrigerator car. Extending across the end of the car and having slidable support by meansof pivot pins 6 norguideways or grooves 7 in the side walls of the car, is the bulkhead or partition A of any desired open `work or perforated construction. Extending from the upper ends of the guidevrays i' horizontally and downwardly to.- ward the adjacent end wall 3 y or grooves S. The lower end of thh bulky car floor.

.ln order to coperate save the upper end of the bulkhead from being forced outwardly by the ice in the ice chamber I provide the downwardly exare guidewavs' head A. normally rests in a groove 9 in the with the pivots and tending abutment hook 10 hinged in a'plate ll supported inian opening 12 in the car roof. As shown in Fig. l this hook normally extends through the upper open work end of the bulkhead immediately belou7 the top of the cross bar 13, so that the cross bar will abut againstthe inner wall of the hook in being forced outwardly by the ice in the ice chamber.

For the purpose of supporting the bulkhead in raised horizontal position underneath the roof of the car, I provide the latches lt'having swivel support l5 in metal casings 16 .in the side walls of the car underneath the roof. The latches 14. are so weighted as to each normally extend outward through the Aopening in the casing 16, -but'will swing inward into the casing under the iniiuence of upward or inward pressure. Consequently as the bulkhead is lifted into ='lotted line position shown in Fig. l it will, in passing the latches, turn the latches inrwardly out of `the way, the 4latches there- Vafter dropping outwardly into position to form rests for the end ofthe bulkhead. The latches are each preferably formed with. a rib 17 .to fit into a correspondin groove y.18 in the bulkhead to more securey lock the bulkhead'in supported position.

In carrying the'bulkhead to supported p0- sition it will tirst be lifted out of the groove 9 and as soon as the upper pivots 6 reach the horizontal guideways 8 .the bulkhead may be swung outwardly, the upper pivots 6 traveling rearwardly 1n the guideways 8 and the lower pivots traveling upwardly in the vertical guideways until the bulkhead is carried to extreme latches let. It will will be freed from t bulkheadl is carried tion it will force the hook on its pivotal support into the opening 12 and out of the Way. y means of this arrangement the upper edge of the bulkhead is'guided horizontally, and a point on each vertical edge thereof intermediate the top and bottom edge is guided vertically, thus causing the bulkhead to recede into its horizontal position. It will benoted that when the bulkhead has receded into its horizontal position its lies directly below the ice aperture or opening 23, 'and since the bulkhead is of open Work con# through which vsaid opening 29 communi.-

raised position past the be evident that as the bulkhead is raised nd swung upwardly it lha hook'lO, and as the to extreme raised posi`l struction it serves as a Ventilating closure4 ice chamber and having notches 20 opening into the vertical guideivays Thus as the bulkhead is raised to a point ivhere the lov/er ivots are o iosite the lates 19 it ma i be4 P Pl P l moved slightly rearwardly to bring the pivots into the corresponding notches 20 and thus support the bulkhead in an intermediate position of rest as indicated in dotted lines in Fig. l. This feature, While allowing the bulkhead to be supported in interi mediate position to gain access to the iiiterior of the ice chamber or to relieve the labor ot' raising, also constitutes a feature of safety in case of accidental dropping ot the raised bulkhead since in case' ot accidental dropping the bulkhead will be stopped in intermediate position and pie vented troni dropping to the floor. Suitable brackets 2l are shown carried bythe end Wall of the car to form rests for the upper end of the bulkhead when in raised position, and thus relieve the strain on the pivots. The rating 22 forming the bottom of the ice ciamber has hinge 'connection 28 with the end wall, and has slotted pivotal con.-

nection 2fl with the extension 25 adapted to turn downwardly to rest upon the car door and form a supporting leg for the grating. The leg extension 25 formed with a shoulder 26 upon which is adapted to rest the outer end of the grating 22 as shown iii Fig. 7. Pivotally secured in the ends oit the grating are lingers 27 adapted to extend into openings 28 in the side walls of the car to hold the grating in suspended position.

Among the advantages et my co tion is the covering ot the ice opening 29 by the bulkhead when the saine is supported in raised position and the consequent seein1w ing ot an open Work protection for the ice opening preventing unauthorized entering therethrough and at the saine time peiniitting of ventilation.
